Armstrong Numbers

An Armstrong number of three digits is an integer such that the sum of the cubes of its digits is equal to the number itself.

For example, 153 is an armstrong number

153 = 13 + 53 + 33
153 = 1 + 125 + 27
153 = 153

Note: Each number is raised to the power of 3, because, the number of digits in 153 is 3.
